Sorry Jondar, I didn't post clearly. What I was saying is that you posted a mileage number, were willing to listen to tips, stated you've tried some things but were still doubtful, and got somewhat hammered for doing so.

Check my post on my 43mpg tank. Granted I'm new here, and from what I can see 43 is a significant number, but I was still called out as either a liar or guy so inept that I must not be able to read a gas gauge.

I'm cool with all of it, as I've got a thick skin, and I like talking Fit tech, and my numbers are consistant.

Look at it this way, you're most likely a record holder!


Onward.

That's not a bad secondary reason, but the real reason is that it was mandated by the feds somewhere back in the dark ages (30 years or so ago). If you've ever worked on or owned a car with a fully- or semi-automatic HVAC system you'll find that they have a "failsafe" mode. Guess what it is? Windshield defrost with AC on. Same reason.

AC dries the air and makes defrost work better. I guess the feds decided that the best thing an HVAC system could do is make it possible to see through the windshield!

No reading comprehension problems, nor attitude... from pcs0snq or myself. pcs0snq made the point that you are likely accelerating and braking too hard. A valid point. He thought you were asking for help, to which you replied...

That's where my comment came in:

Cynical? Sure! A valid point I made though, illustrating the dichotomy between where you posted (Eco forum), and the content of your post. Why post in the eco forum if you bash the only good advice given (pcs0snq's advice)? Nonsensical. Therefore, I used a litote as a literary device to convey my point.

Eh... Try pcs0snq's advice. Accelerate slower, lay off the brakes, and pump up your tire pressure to allow you to coast a little more.

I see...so it's just selective reading then, as neither of you saw (or just chose to ignore)

You folks tout 40+ mpg and 500 miles tanks in your sigs and expect it to be taken on faith, but refuse to extend the same courtesy to me when I say I'm already driving extremely conservatively? Maybe I need to post a photo of a dash with an empty fuel tank and 550 miles on the trip odometer in order to be believed.

Eh... Let me know your results on the run I described, or accept that all the little tricks only work in a limited environment that doesn't apply to everyone's world. Again, the suggestions offered were appreciated, but are already in place. Next?

Another thing to take into account with stop-and-go driving is weight. Have you removed all excess weight? What about going to carbon fibre for the hood or hatch? Just a suggestion, since I think weight is probably a big cause for your fuel economy.

Not a bad idea. He's loading the car up with newspapers, so if he can counter that weight gain with a weight reduction elsewhere it might make a difference.

Another thing I just thought of would be to force the car to shift earlier than it does on its own. Speed and acceleration probably don't matter much in a paper delivery situation so forcing a shift at, say, 2500 RPMs or less might also make a difference.

The car does have a weight limit on the inside door placard of 850LBS(not sure if that is the exact number or not). You can always get some stiffer springs or a fully adjustable suspension along with light weight componts such as mentioned or remove all interior.

Very good point on the weight...there are times I really miss my '84 CRX.

The magic seats were one of the things that make it a great car for paper delivery, but I wonder how difficult they'd be to take out/in altogether. For 99% of my use they may as well be sitting in the basement. Will need to do some research.

The early shifting might work sometimes, but it'd probably be situational unless I keep it in Sport mode full time. The times I've tried it in Drive, it wants to re-downshift if I'm still accelerating any little bit. Not that running in Sport mode would necessarily be a bad thing. If I'm getting any benefit from DFCO, I could lose it if the rpms drop too low though, yes?

Oh, and the small idle surge going into park does *not* happen going into neutral. That eliminates the idea that it was due to taking the trans load off the engine I guess. I'll probably start using neutral and the handbrake more often.
